.Be it known that I,:JOHN1RANK,: a citizen of the'United States, res'iding=atTMinneapO-;

lis, in the county of Hennepin and State-of- Minnesota, have invented certainlnew and 'useful Improvements in Grease-Gups;'- and I do hereby declare the following-to be a full, clear, and exact description of the in vention, such as will enable'others skilled in theart to which -it"appertains,to make and use the same. v

My presentzinvention relates to grease cups for journals and bearings generally, but is particularly designed-as an improve menton that type of grease cupswlrieh-is disclosed and broadly claimedin myprior Patent No. 901,039, ofedate, Qctober 13th, 1908. T'

Generally stated, v the invention consists of the novel devices and combinations .ofde vices hereinafter described dIld I defined in the claims. 1

Int-he said-prior patent wthetgrease cup was provided with :a detachable-cover, a feed rod extended through the cover-and the discharge nipple of thecup, stop collars on said fed rod above and below :the cover,-

. and a fed head adjustable on sa-id feed rod:

, rectly-secured on'the said sleeveyland the said sleeve is-provided .withimean's for ador. seats in difierent hearings or journals.

.which connects with the cup, but the other ends of the said nipples aremade'in difi'erent sizes so as to fit different threaded sockets Inthe accompanying drawings which illustrate the invention, like characters 1n-. l

dicate like parts =throughout the several viewsp plied toza crank-rod and wrist pin journal;

Fig. 2 is aside elevation-of a=cup showing the same removed from the journal; Fig. *3 1s a side. elevation, ofzthe body ofthecup,

- other parts being removed ;.:Fig.-4is a.frag-" mentarysection OHthGrllHB w m. of Fi 3; F1g. 5 showsthe-fe.ed rod andthe feed ead with its long sleeve, "the latter being sectioned; and .6 is .a detail in section showing one of the interchangeably usable nipples-of. the 'feed cup.

The numeral 1 'indicates a-crank shaft 'havinga crank 2 with an ordinary wrist pin pin 3. of these parts are, or may be, of

standard or. any suitable" construction.

;The 'body'o fthe :feed cup, or-in other 'Words, the feed cup-proper, is indicated by the numeral 6 and. is preferably of the. form shown-in'the drawings. At its contracted lower-iend, the said feedzcupfi 113,513.11 internally threaded-seattthat is adapted to receive one end of a nipple7, which is threaded at .both ends, and preferably; formed with .an

intermediateangular portion 8-to which a -wrench.-may be-applied. :The loweror ex- .tendedend of the nipplesisthreaded at 7* .toadaptit to'bescrewed into a correspondingsliyi threaded seat 'in-the bearing,to-wit, as 'own intota' ,strapt of the crank rode. The said nipples will be made with threaded: ends 7 of-ditferent diameter, so that they will fit threaded seats .of different sizes. This adapts the. grease cup to-be easily and quickly applied to vbearings or journals having threaded seats of. different diameters or threads of difi'erentpitch simply by selection of a proper-nipple, and without making it necessary to .carry as large a stock of grease cups as would otherwise be necessary.

The cover 9 of the grease cup ISEPIBfBl" ably detachably secured to the cup byan ordinary bayonet joint 10, although it; may be otherwise secured. I

The feed rod 11 isPreferabIy-made. from copper, and is passed through an axial perforation in ..the cover 9,. through the nipple 7, and through a suitable passage 12in the preferably of conical form. This feed head 13, in accordance with my invention, and as already stated, is provided with a long sleeve 14 that is extended through the axial passage in the cover 9. At its upper and outer by setting the stop collars'16 and 17 in en-- end, the sleeve 14 is provided with a set screw 15 for rigidly but adjustably securing said sleeve andfeed head on the said rod. Stop collars 16 and' 17 are adjustably secured on the sleeve 14, respectively, below and above the cover 9, preferably by means of set screws 18.

The amount. of grease or oil that will .be fed to the journal will depend first, on the amount of endwisemovement which is permitted to the rod 11 and feed head 13 which is carried thereby, and second, it will also depend on'the distance that the said feed head is normally set awayfrom the cooperating end of the nipple. The amount of endwise movement which will be given to the feed rod and feed head is determined by the adjustments of the collars 16 and 17 in respect to the cover 9. In most instances, the said collars will be so set that more or less endwise movement ofthe feed rod will be permitted, but for very high speeds, it frequently is desirable to secure the feed rod and feed head against endwise movements. And this, as is evident, may be accomplished j gagement with the said-cover 9; When this is done, the amount of oil that will'be fed will depend on the adjustment of the feed :head 13 in respect to the nipple. Usually I the wrist pin or rotating member of the jour- -nal will be provided with a peripheral oilway or groove which will pass the lower end of the rod 11, and hence, the outer stop collar 17 is usually so adjusted that the lower end of the said rod 11 will lightly engage the rotating member of the journal but cannot drop into the oil-way thereof.

With this improved arrangement, as already stated, the sleeve 14, and hence the feed head 13 thereof, may be adjusted on the rod 11 without removing the cover 9 and without getting the fingers into contact with the grease which is contained within the cup; Even when the inner collar 16 is to be adjusted,it is only necessary to raise the cover and rod and the said inner collar can then be adjusted without digging deep into the grease, and without entirely removing the rod or the sleeve from the grease.

The interchangeable nipples above described, are capable of use on grease cups generally, regardless of whether or not they are provided with the improved feed rod and sleeve.

What I claim is:

1. The combination with a feed cup having a cover and a dischange,passage, of a feed rod extended through said discharge passage, a sleeve adjustably mounted on said rod'extended through said cover, and means for adjustably securing said sleeve'in respect to said cover, operative from the exterio'r of said cover.

2. The combination with a feed cup having a cover and a discharge passage, of a feed rod extended through said discharge passage, a feed head on said rod, having a sleeve extended through said cover, and means for adjusting said feed head and sleeve from the exterior of said cup.

3; The combination with a-feed cup having a cover and a discharge passage, of a feed rod extended through said discharge passage and through said cover, a sleeve on said rod extended through said cover, means for adjustably securing said sleeve on said feed rod from the exterior of said cup, and

means for adjusting said sleeve in respect to i said cover.

4. .The combination with a feed cup having a cover and a discharge nipple, of a feed rod extended through said discharge nipple and cover, a feed head on said rod cooperating with said discharge nipple and provided with a long sleeve extending through said cover, means applied to the outer end of said sleeve for adjustably securing the same on said feed rod, and stop collars, one above and one below said cover, adjustably secured on saidsleeve.

5. The combination with a feed cup having a detachable cover anda discharge nipple, of a feed rod extended through said discharge nipple and through said cover, a feed headon said rod cooperating with said discharge nipple. and provided with a long sleeve also extended through said cover, stop collars onsaid sleeve one above and one be low said cover, and set screws applied to said 7 .collars and to said sleeve for adjustably securing said collars on said sleeve and said sleeve on said rod, thesaid screw for securing said sleeve being located above said cover and the upper collar, substantially as described.
